Police officers who called to the house, near Glasgow, last week reportedly saw the family’s pet Chihuahua levitating and clothes flying across rooms.
The mother and teenager contacted officers after being left "extremely distressed" by the "violent and unexplained circumstances", according to insiders.
A baffled source said: "These were incidents that were witnessed by our own officers. Incidents that are not easily explained.
"But officers with more than 20 years' service are saying they've never seen anything like this.
"It really is something that down-to-earth police officers are having trouble getting their heads round."
